Energy storage has been touted as the enabler of high levels of intermittent renewables in the electricity system – the silver bullet or Holy Grail for solar and wind. A key attribute for the technology’s deployment will be scalability, writes Melissa Lott.

PV Tech Storage interviewed Bill Radvak of American Vanadium, whose company has a plan to scale up flow batteries for renewable energy integration, using its own vanadium deposits.

In a two-part video interview with PV Tech Storage, Wolfram Walter, founder of battery manufacturer ASD Sonnenspeicher, said electricity storage suffered from an image problem. He describes to Andy Colthorpe how his company is marrying cutting-edge technology with cool design to appeal to a broader market.

The battle of the chemistries has long been alluded to in the energy storage space, and nowhere with greater frequency than with reference to battery chemistries.

This year’s Intersolar Europe event in Munich will have an area dedicated energy storage. As the event gets underway, Andy Colthorpe spoke to Bryan Ekus of the International Battery and Energy Storage Alliance to get his views on an increasingly important technology.

Hawaii is inviting proposals for up to 200MW of storage in the face of regulatory demands and unprecedented distributed generation challenges. As Dean Frankel writes, the process could offer some answers to the conundrum of integrating higher volumes of renewable energy generation.

Electrical storage has been much hyped as a key technology in the ongoing deployment of solar. But as Andy Colthorpe reports, with take-up of the technology so far only patchy, the coming year will be a crucial one for storage to prove its worth.

Neither commercial-scale nor energy storage have yet take off in the US. But as Felicity Carus reports, this could be about change as companies eye opportunities in both segments.
